Thanks for reinforcing my earlier comments there, Chris. smile

Not so sure about "patient safety" and "higher grades", though.

As I must have said on here many times before:- "patient safety" is what "biomed" is all about, and anyone who thinks differently just doesn't cut the mustard (as far as I'm concerned). Why do you think those guys I mentioned got shown the door?

But in regard to "higher grades" ... what are you talking about Chris? IQ? Medical Physics staff?

Who are the "lower grades" then - those with "only" an ONC or City Guilds? Or are you thinking of NHS Pay Grades (a pretty poor indicator of actual worth, in my experience)?

And ... how does the VRCT model overcome any of this stuff? think

But at least you've mentioned patient dosage there, so thanks for that:- at long last we've heard a sensible hint at what all those thousands of risks to patients could actually be. Do we have any more?
